Abstract:
Linear terminal alkane-diols have been shown to function as more efficient substrates of the transglycosylational activity of NAD+ glycohydrolase (NADase) than the corresponding respective 1-alkanols. A series of eight alkane-diols from ethane-1,2- to nonane-1,9-diols underwent an O-ADP-ribosylation in the incubation reaction with NAD/NADase to provide the corresponding ribosylated products. The structural properties of these products were characterized by 1H NMR and MS spectrometries. No substantial double ADP-ribosylation of the two hydroxy functions was observed which was initially expected in the diols of higher carbon number.
